Codex
OpenAI's coding-oriented agent and model line used for reading repositories, editing code, running checks, and collaborating on software tasks.
Codex is designed for software engineering workflows rather than generic chat alone. A coding agent needs repository context, file-editing tools, terminal access, test feedback, and clear rules for respecting user changes.
The value of a coding agent depends on its operating loop. It should inspect the codebase before changing it, make scoped edits, run relevant verification, and report both what changed and what could not be checked.
